WATER-HEATER.

Specification of Letters Patent.

Patented April 16, 1907.

Application led February 15, 1906. Serial No. 301,211.

l l l r l l l City, in the county of Jackson and State of Missouri, have invented certain new and useful Iiiipi'ovements in lVater-Heaters; and we do hereby declare that the following is a full, clear, Iand exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of the invention is, first, to subject the water to be heated to a broad heating-surface in an area upon which the heat lis concentrated; second, to increase the water circulation, and, third, to employ heat-dellecting surfaces within the heatingreceptacle.

struction and combination of parts such as will be firstfullydescribed,and then spec1lic ally pointed out in the claims.

of the improved water-heater embodying a top plate 10 and a bottom 12. In the top 10 is an opening 14, located at a point e uidistant from the sides of the receiver, an in the bottom 12 in a vertical line with the opening 14 is an o ening 15, slightly larger in circumference t ian the opening 12, in which opening is inserted a cone-shaped airtube or duct 16, and secured at the ends to the sides of the respective openings.

With the side of the receiver 9 is connected one end of a short tube 17, the other end of which tube extends through, an opening 18 in the sides of the case 5, in which tube exi larger end portion of which extends from the The invention consists in the novel contop 10 of the recciveraiid near the outer edge of said top upwardly to within a short distance of the top 6 of the case or shell 5.

27 indicates the water-intake or threaded nozzle upon the outer side ofthe case 5 with which the water-service pipe is connected.'

Vith this nozzle is connected the outer end l of the 'independent coil of pipe 28, which eX- tend through the casing 5 and shell 22 below Within the case 5 and supported by the the water-space, the coil of pipe 28 being adjacent to the top 10 of the gas-burner 9, and which consists of a cylindrical receiver the sides of which extend upwardly a short distance and with which sides are connected l the inner end of the coil is extended through the inner shell 23 in communication with the water space or chamber 26 at a point a short IOO portion of said s hell` With the inner shell 23 at a point a short distance downwardly from the upper portion of the shell is connected the upper end 29 of a coil of'pipe 30, which coils are arranged in a vertical endeiit position, the sides of the coils eing drawn inwardly, saidcoils being su ported at a point a short distance downwarr. ly from the point of connection with the shell 23, the

other end 31 of which coil extends downl wardly nearly to thc to 10 of the burner and and extended through the shell 22 below the point of connection of the innershell 23, thence through the outer shell and provided with a nozzle or connection 32 for the waterdistributing pipe. The portion 3.1 of the ipe 28 is also tapped at a point inwardly rom the nozzle 32, and a nozzle 33,`connected with the ipe,tl1c nozzle extending through the slde o the shell 22 and the outer eas-ng 5,-

thus affording diverse directions for the 'distribution of heated water.y

In the top 6 of the case 5 is an lopening' 34, through'which extends then per end of a draft-tube 35, the lower end ofpwliich tube is outwardly deflected or cone-shaped and extends within the case to a position concentric withthe upper. end of theV shell 22. The gas for ignition is sup lied from a suitable source through the suppiyipe 19 to the burner 9,

the regulation in tie quality being maintained.- and the. .quantity reduced and increased by, the usual gas-regulating valve. (Not shown.) The gas which enters the receiver in burner 10 is ignited above thetop andthe iiarnel is'concentrated upon and'delected from one to the other inner surfaces of the ,shell 23 and u on the u per inwardly-inclined vsurfaces o said shell. The water is supplied through. the coiled pipes 28, and being subjected to heat vthe water is heated initially and prevents subsequent sweating in 'l the receptacle, enters the Water-space 26, and

the space being contracted toward the end of the shell the passageupward o fifi water is accompanied with rapid increase in E temperature within the area of theheated surfaces of the shell, thence passes through the coils 30, the surfaces of which arel directly in the path ofthe Haine, and therefore exposel, the flame `being fed with air through the air-ductl, the heat being retained within the case 5. Thelieater is adapted to afford heated water for inst-antaneous use indwellings andlwhenever its use is required with economy in the quantity of fuel necessary to obtain the higher temperaturesof water.`

In our invention the heating-coilis inde-- pendent of the water-circulating coil, so that the water before entering the water-chamberA becomes hot and in the circulation of vthe heated water drives the water ahead or upis celled 1n the reverse c ireetion to the co1] 2S wardly within the water-chamber without meeting resistancefrom a cold-water supp-ly i from a cold-'wa'ier-supply inlet. In our 1nven'ticn allthe water is heated before entering the pendent coil,.upon which the heat is lconcentraed and from whence discharged.

Such modifications of the invention may be employed as are within the scope ofthe invention.

Having fully described our invention, what we now claim as new, and desire to secure by Letters Patent, is-' '1. In a water-heater a water-receptacle comprising outer and inner concentric shells having a water-chamber between said shells a water-heating coil within the receptacle connected at its upper end with the upper poriionof said water-chamber and the lower discharging end of said coil extending outwardly from said receptacle below the said water-chamber, an independent heatingcoil within the said receptacle having one end connected with the lower portion of said water-chamber and the other end extending outwardly from vsaid receptacle below the said water-chamber and connected the source of sulpply ofwater and means for heating said coi s. l

2. In a water-heater ya receptacle for the water comp rising outer and inner shells having a water-chamber between said shells and the up er portions of said shells reduced in circumference a pendent heating-coil Within the upper portion of said receptacle having one end connected with the upper portion of said water-chamber and having `the lower 'discharging end of said coil extending outwardlyfrom said receptacle an independent heating-coil within the receptacle at the lower end thereof having one end vconnected with the lower portion of the water-chamber IOO IIO

and the other or discharging end extending l outwardly from said receptacle and connected with the source of liquid supply and means for heating said coils.
